<p>A magnetic confining apparatus (20) prevents the escape of molten metal through the open side of a vertically extending gap (25) between two horizontally separated members (21,22) and in which the molten metal is located. The apparatus includes a current conducting coil (30) for generating a horizontal magnetic field and non-magnetic fins (44) for concentrating the current in the surface of the coil (30) which is closest to the open side of the gap (25). The magnetic field generated by the apparatus extends through the open side of the gap (25) and exerts a confining pressure against the molten metal in the gap. <IMAGE></p> |
